internet communities

What are online communities? I am not so sure. One thing I can tell you is when I hear those words I usually think of chat rooms. Everybody knows that one thing what everybody can do is go to the chat rooms.There are many different chat rooms. I remember my friends telling me how much fun it was. I wondered what was so fun about it.If I want to talk to some of my friends,why I just pick up the phone and call them?They sed, it is a fun because you can talk to people all over the world.One of the first things you have to do to get to chat room is create your screen name.It was fun ,it took me almost 20 minutes to create one. There are millions of them to choose,and it is annoying when you finally pick up one and it's already taken.After I picked up my screen name I went to a chat rooms.Some of them were interested ,some not.I think that there is a category for everyone.One of the reasons why people go online is because they can to pretend to be anyone. A person who might have a low self-esteem or be shy might feel comfortable enough to start talking to other people. Also many kids go online because when you are young most parents will not let you go out at night. Even though chat rooms have their pluses ,they have also their negatives.Especially young people have to be careful who they talking to.Ther is a lots of crime on internet.
